The use of biometric systems has been increasingly encouraged by both government and private entities in order to replace or improve traditional security systems. Iris recognition biometric systems have proved to be efficient at personal recognition with highest recognition accuracy. This paper presents an up-to-date survey of iris segmentation algorithms that had been developed in literatures. It discusses the centrality of segmentation stage to effectiveness of iris recognition system. It identifies the methods used in the segmentation algorithms, database(s) on which the algorithms were used, the accuracy of the method and some noticed limitation(s) of the reviewed algorithms. Through this, it is able to identify the gaps for further researches in the field of application of iris recognition system in computer security.
